Application March 3, 1941, Serial No. 381,450

1 Claim.

This invention relates generally to a device and method for assisting a person to keep comfortable in warm or hot weather.

The main object of my invention is to provide a device and method for assisting the body to dissipate excess heat in a simple and effective manner. This object involves furnishing a cool environmental factor in the form of my device.

Another object is to provide a device of this kind that is sanitary.

Another object is to provide such a device and method that is safe for general use, incorporating proper insulation of the dry ice or other refrigerant.

A further object is to provide such a device that may be used without harm to the body or clothing.

Another object is to provide such a device and method that adjusts itself to the temperature of the body in nowise disturbing the balance between thermogenetic and thermolytic functions.

Other objects and advantages will appear from the description to follow taken in connection with the accompanying drawing in which- Fig. l is a proximal view of a right arm of a person on which is mounted a device embodying my invention.

Fig. 2 is a front view of the improved device, parts being broken away for the sake of clearness.

Fig. 3 is a sectional view on the line 3--3 of Fig. 2.

Fig. 4 is a perspective view of the sponge rubber sack.

Fig. 5 is a sectional view of the sack shown in Fig. 4 on the line 5--5 of Fig. 4.

In carrying out my invention I provide a fabric bag or envelope II] to which is suitably fastened an elastic arm band II. The bag may of course be of any desired shape, and instead of an elastic arm band, a strap and buckle or other suitable fastening means may be used. The bag has an opening at its top which is closed by a flap I2, which flap may be fastened to the body of the bag by a snapbutton or other suitable means.

Mounted removably in the bag is a sponge rubber container or sack M. This sack is slitted along a portion of its periphery which opens into a chamber or compartment I5 inside of the sack. In the chamber or compartment 15 is placed a cake or cube l6 of a suitable refrigerant, such as dry ice.

My improved method contemplates that the improved device be worn in pairs on opposing members of the body; that is, one is placed on each arm, or on each wrist, or on each thigh, or on each ankle, etc., as desired, but may be used singly on any of various body surfaces. However, I prefer to place my improved device on the arm I! as illustrated in Fig. 1. In such case, the device is placed on the upper arm immediately above the eminence caused by the biceps brachii. The bag In is placed on the inside of the arm approximately over the area under which courses the brachial artery.

I have found from experiment that my device does not lower the body temperature even a fraction of a degree; that the use of the device causes no imbalance between the thermogenetic centres and the thermolytic centres of the body, and that my improved device merely assists in the work of the thermolytic function, literally absorbing some of the excess heat from the blood stream through the superficial tissues of the body at the point or points where the device is worn.

I claim:

A device for dispersing excess heat of the human body including a fabric envelope having an opening at one end thereof, an integral foldable flap for closing said opening, a sponge rubber member having flat sides and a circular periphery and. having an interior compartment between said sides With an entrance on the circular periphery, said compartment being adapted to hold removably a cake of refrigerant such as dry ice and an annular elastic band fastened to the fabric envelope substantially at its center for supporting the envelope on a part of the body.
